To (all whom it, may concern.-

Be it known that I, FERDINAND WEsEL, a

citizen of the United States, residing at New York, (Brooklyn,) inthe county of Kings and State of New York, have invented certain new and useful Improvements in Machines for Shaving Electrotypes,Stereotypes, &c., of which the following is a specification.

This invention relates to certain improvements in machines for shaving off stereotype and electrotype plates and blocks either pica high, block high, or type high, or other height, as required, by a simple, quick, and effective adjustment of the knifehead of the machine in such a manner that the accurate shaving of a plate or block'is accomplished so as to avoid any tilting of the plate or block when the knife arrives at the end of its out; and the invention consists of a machine for shaving stereotypes and electrotypes the knife-head of which can be quickly adjusted by suitable gages so as to shave either pica high, block high, or type high, as required, said knife-head being provided with adjustable spring-cushionedrollers at some distance from the shaving-knife and by which the plate or block is held in position against tilting during the cutting action of the knife and when the same arrives at the end of its out, as will be fully described hereinafter, and finally pointed out in the claims.

In the accompanying drawings,Figure 1 rep resents a side elevation of my improved stereotype-shavin g machine. Fig. 2 is a front elevation of the adjustable knife-block, showing Figs. 3 and 4 are vertical transverse sections, respectively, on lines 3 Sand at 4, Fig. 5. Fig. 5 is a horizontalsection on line 5 5, Fig. 3. Fig. 6 is a verticaltransverse section, drawn on a larger scale, showing the knife in the act of shaving ofi a stereotype-plate and the spring-actuated plate-holding roller at the end of the same;-and Figs. 7, 8, and 9 are top, side, and sectional views (the latter on line 9 9, Fig. 7 of one of the gages for permitting the adjustment of the knife-head and knife so as to shave either pica high, block high, or type high.

Similar letters of reference indicate some sponding parts.

Referring to the drawings, A represents the supporting-frame of my improved machine for shaving stereotypes, electrotypes, or other matter. On the frame A is supported a bedplate B, which is of oblong shape and large enough to support the different sizes of stereotypes to be shaved. The end of the stereo* type-plate abuts against a tranverse abut ment or work-rest b at the front end of the bed-plate B, whereby it is held in position during the shaving action of the cutting knife. The shavings are collected in a suitable box or receptacle beyond the work-rest 1'). (Not shown in the drawings.)

Along guide-rails d at the sides of the bedplate is guided the transverse support D'for the knife-head, said support being provided with grooves at, so as to fit'on the guide-rail d. The support D is provided Withrecesses 01 in which are guided the lugs e of the knifehead E. The knife-head E is guided along the inclined faces of the transverse support D'by means of ways e, that are arranged at both sides of the support and attached thereto by suitable screws, as shown in Fig. 5. The shaving-knife E is placed against a raised portion of the knife-head E and attached to the same by means of headed screws e ,which pass through slots c in the shaving knife. The upper end of the shaving-knifeE is acted upon by adjusting-screws f, which turn in lugs f on the face of the knife-head E, so as to readjust the knife on the knife-head after sharpening the same to the exact position re quired. The knife-head, together with'the knife, can be quickly raised or lowered by means of screw-spindles F,which pass through the lugs e at the rear of the knife-head Eand which are operated by means of gear-wheels F at their upper ends, said screw-spindles being retained in bearings of the transverse support D by means of shoulders on the spinary pointer or index I, attached to thecen tral front part of the knife-head, said index being curved in backward direction, so that its point is in front of the hand-wheel F By turning the hand-wheel in one or the other direction the knife-head is raised or lowered on the inclined face of the transverse support D, according to the thickness of the plate or block which is to be shaved. At both sides of the support D, at the corners of the same, is arranged an axially-adjustable triple gage G, which is provided with three lugs, of which two, G G are for pica and type high adjustment and are arranged in line with each other and the other lug, G for block-high adjustment,which is arranged at right angles to the two others, as shown clearly in Fig. 7. The triple adj ust-ing-gage G,with its three blocks, is swiveled to a headed pivot-screw g, Figs. 7, 8,and 9, so that the gage can be readily turned on the said pivot, so as to present any one of its three lugs to the laterally-extending stoplugs g, Fig. 2, at the upper end of the knifehead E. When it is desired to adjust the knife-head and its knife to the required thickness for pica or block, the knife-headisraised by the hand-Wheel and its intermediate transmitting-gearing sufficiently so as to permit the turning of the gages so that the lug of the proper size is presented,after which the knifehead is moved by turning the hand-wheel F in opposite direction in contact with the respective lug, so that the knife-head is thereby directly and quickly adjusted into the required position. When, for instance, the knife-head is to be adjusted to type-high position, the lug corresponding to this position is placed under the lug g, and thereby the knife head and its knife adjusted to the stereotype-block of. that height. Whenthe knife is to be adjusted to block high, the lug corresponding to this position is placed under the stop-lug g, so that the knife is set directly for shaving a stereotype-block blockhigh. When, however, the knife is to be set for pica high, the smallest lug is placed below the stop-lug, so that the knife is in its lowermost position and arranged for shaving stereotype-plates pica high.

The triple gage G may be provided with a spring-actuated pin g that is provided with a pointed end, so as to take into small conical depressions 9 arranged in the upper corners of the supportD,equidistantly from the pivotpin g, so that the gage is held in proper posi tion by the locking action of the pin.

The adjustment of the knifehead by the gearing described, in connection with the triple gage, permits the quick and reliable adjustment of the knife-head to the blocks or plates to be shaved and produces the gradual shaving of the back of the plate to the required thickness until the stop-gages arrive on their respective lugs of the gage and terminate thereby the shaving action on the plate, for the reason that the same is reduced to the required thickness by the successive shaving action of the knife as set by the hand- Wheel and intermediate gearing and screwspindles of the knife-head.

When the size of the lugs G G G of the gages differs from the thickness of the block to be produced, then the hand-wheel is turned for a certain number of graduations, as indicated by the pointer I.

The knife-head E is provided, in addition to the rear lugs at its rear sides, with boxes h, in which are guided the shanks h of bearings ha, in which the transverse rollers H are supported The shanks of the bearings are guided in the lower ends of the guide-boxes and provided with interiorly-threaded s0ck-. ets,which are engaged by spindles h ,threaded at their lower ends so as to engage said sockets, said spindles passing through the closed top of the guide-boxes h and being provided with shoulders 71. above the same. The upper squared ends of the spindles 77/ extend through openings in the support D, so that they can be readily taken hold of by a suitable tool for adjusting the roller-bearings higher or lower relatively to the guide-box, as required for the position of the roller relatively to the knife-head. Between the shanks of each of the roller-bearings and the upper end of the guide-box h is interposed a helical spring h which exerts a cushioning action on the roller H. The roller projects in a plane below that of the edge of the shaving-knife, in which position the collar 72, abuts against the upper closed end of the guide-box h, as shown in Fig. 4. During the motion of the knife over the back of the stereotype plate or block the roller is pressed upwardly against the springs, and is thereby pressed tightly on the plate so as to hold the same in position and prevent it from shifting laterally or from tilting when the knife arrives near the end of the stereotype, which in the former construction of shaving-machines has been a very objectionable feature. By means of the roller the shaving action on the plate is made steady and reliable, the plate held throughout the shaving action of the knife firmly in position on the bed-plate of the machine, and injury to the type avoided when the knife arrives near the end of the plate, as any tilting of the :plate is prevented by the pressure of the roller on the back of the stereotype plate or block. The roller is an important and valuable improvement in shaving-machines of this class, as it is adjusted with the knifehead, and it remains in a proper relative position to the knife-head, it requiring only adjustment in the guide-boxes, when, after the shaving-knife is sharpened or its position changed on the face of the knife-head, the corresponding readjustment of the pressureroller has to be made.

At opposite sides of the support D of the knife-head are rigidly attached two racks R, which extend in backward direction at both sides of the bed-plate, said racks being engaged by means of pinions R on a drivingshaft S, which is either set in motion by handles operated by hand-power or by means of suitable transmitting gear-wheels from a beltdriven power-shaft, according as the machine has to be operated by hand or power. The machine is further provided with treadles for reversing the motion of the machine when it is arranged as a power-machine, so that the forward and backward travel of the knifehead is produced by the reversing of the motion-transmitting gearing. As this feature is well known in stereotype-shaving machines of this class, it is not illustrated in the drawings nor claimed in this application.

The machine is operated as followsz The stereotype plate or block is placed downward on the bed-plate, its end resting against the work-rest b at the front end of the machine. The knife-head is next adjusted to the proper position, together with its knife and pressure roller, by the hand-wheel, the gage being first set in position, so that the required size of block is presented to the stop-lugs g at the upper corners of the knife-head. The machine is then set in motion, so that the knife, with its support, is made to travel forward and backward over the stereotype plate or block, so that the shaving cut is made. This shaving cut is repeated until the stoplugs g abut against the lugs on the gages, whereupon the shaving action is completed. "The stereotype is then removed and another one placed in position. When the thickness of the stereotype changes, the knife-head has to be adjusted by presenting the corresponding lugs of the gages to the stop-lugs and then repeating the former action. During the shaving action the pressure-roller holds the stereotype firmly in position in the bed-plate,

as before described.

The advantages of my improved shavingmachine are- First. That the various sizes of stereotypes can be quickly shaved pica high, block high, or type high, as the adjustment of the knifehead is quickly and accurately accomplished.

Second. The arrangement of the pressureroller at the rear of the shaving-knife holds the stereotype firmly in position and presents the same in a better manner to the action of the shaving-knife than heretofore.

Third. By the convenient adjustment of the knife-head and pressure-roller all the parts can be individually adjusted as required.

Having thus described my invention, I claim as new and desire to secure by Letters Patcut-- 1. In a stereotype-shaving machine, the combination, with the support, of a knifehead guided on the same, a knife on said knife-head, adjustable gages on said support adapted to arrest the knife-head in its downward motion, and means for moving said knife-head along the support until arrested by the gages, substantially as set forth.

2. In a stereotype-shaving machine, the combination, with the support, of a knifehead guided on the same, pivoted gages on said support, said gages being provided with lugs of different sizes, a knife supported on the face of the knife-head, stop-lugs at the ends of the knife-head, and means for raising or lowering the knife-head until the same is arrested by contact with the stop-lugs of the gages, substantially as set forth.

3. In a stereotype-shaving machine, the combination of a reciprocating support, a knife-head guided on said support, a knife on said knife-head, and a yielding roller located back of the knife and below the edge of the same, substantially as set forth.

4. In a stereotype-shaving machine, the combination, with a reciprocating support, a knife-head supported on said support, a knife attached to said knife-head, a spring-pressed roller located back of the knife-head and below the edge of the same, guide-boxes for the shanks of the roller-bearings, and screw-spindles for adjusting said shanks so as to adjust the roller to the required position relatively to the edge of the shaving-knife, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.

FERDINAND WESEL.
